Performing bronchoscopy in cetaceans is challenging but feasible for diagnosing respiratory infections. This study details the procedure in dolphins and whales, aiding future veterinary care.

Area of Science:

  • Veterinary Medicine
  • Marine Mammal Science
  • Respiratory Physiology

Background:

  • Lower respiratory tract infections pose significant health risks to cetaceans.
  • Obtaining respiratory samples from cetaceans for diagnostic analysis is difficult.
  • Bronchoscopy is a valuable tool in respiratory medicine across various species.

Purpose of the Study:

  • To describe the application of fiberoptic bronchoscopy in cetaceans.
  • To document the feasibility and technique of bronchoscopy in dolphins and whales.
  • To provide guidance for clinicians performing bronchoscopy on marine mammals.

Main Methods:

  • Fiberoptic bronchoscopy was performed on three bottle-nosed dolphins (Tursiops truncatus) and one false killer whale (Pseudorca crassidens).

  • The procedure involved visualization and sampling of the lower respiratory tract.
  • Detailed observations of the technique and animal responses were recorded.

    • Main Results:

    • Successful fiberoptic bronchoscopy was achieved in all four cetacean subjects.
    • The procedure allowed for direct visualization of the tracheobronchial tree.
    • Insights into the practicalities of cetacean bronchoscopy were gained.

    Conclusions:

    • Fiberoptic bronchoscopy is a viable technique for examining the respiratory system of cetaceans.
    • This procedure facilitates the collection of lower respiratory tract samples for diagnostic purposes in marine mammals.
    • The reported experience serves as a foundational guide for veterinary professionals working with cetaceans.
